To upload files to Salesforce from a React UI bundle with progress tracking, use the provided upload() API with an onProgress callback to surface pending, uploading, processing, success, and error states directly in your UI.

You can upload files and link them to Salesforce records immediately by passing a recordId to the upload() API. The API returns a contentBodyId and optionally creates the ContentVersion record for direct linking during the upload process.

Yes, you can upload files to Salesforce Content and defer record linking. Use the upload() API without a recordId to get a contentBodyId, then manually create the ContentVersion and link it to the record after record creation is complete.

No, the upload() API is completely API-only and workflow-agnostic. You build your own custom React UI components, such as file inputs or drag-and-drop zones, around the exported upload functions without forced UI constraints.

Yes, the Salesforce file upload API supports uploads targeted to the current user profile. It handles three distinct patterns: direct-to-record uploads, deferred record linking, and current user profile targeting using the upload() function.

The upload() API returns a contentBodyId which must be integrated with ContentVersion creation. You can optionally create the ContentVersion via recordId during the upload, or manually create it later for deferred record linking.
